DESCRIPTION:
Luigi Auriemma has reported a vulnerability in the Unreal Engine,
which can be exploited by malicious people to compromise a user's
system.

The vulnerability is caused due to a boundary error within the
"UGameEngine::UpdateConnectingMessage()" function, which can be
exploited to cause a stack-based buffer overflow by e.g. tricking a
user into connecting to a malicious server.

Successful exploitation requires that downloads are enabled
(default).

The vulnerability is reported in the following games:
* Unreal Tournament 2003
* Unreal Tournament 2004
* Postal 2
* Rainbow Six: Raven Shield
* SWAT4

SOLUTION:
Do not connect to untrusted servers.
